Is there a way to get the length of a slack call from the API? In the app, I can see a call lasted 15 minutes but the API response for calls does not seem to include a time length. We are using the conversations.history endpoint with a user oauth token. We've tried pulling a call up both from a larger list or asking for the call's conversation message by it's timestamp value. Here is an example of a phone call as returned by the Slack API:
